Abstract

Abstract This modular element is particular suitable for equipping false ceilings, partition surfaces and non-structural walls in general. The element comprises a main body having, on its outer surface a pair of male connection elements and a corresponding pair of countershaped female connection elements. Each of the male connection elements comprises a flat ribbing extending from the outer surface of the main body and has, on an edge thereof opposite to the outer face, a substantially cylindrical enlargement, while each of the female connection elements comprises a tubular lug having its longitudinal axis parallel to the enlargement of the male connection element. The lug of the female connection element, on a side thereof opposite to the outer surface has a longitudinal slit extending from an open end of the lug for accommodating the ribbing of an adjacent modular element.
